Expectation: arrow should disappear from empty folder :question:

@TheOneRing the expectation in this issue does not met. Will there be a fix to meet the expectation or arrow in the empty folders are expected (arrow will not disappear)?

The problem is that we do a propfind for only the current level. So in the example above, "myfold" is initially not expanded. When it expands, we do a propfind, get back "empty" and "ufold", but we don't know if they have subfolders, so we show the indicator. We only know that "empty" is empty when it is expanded and the propfind returns 0 (zero) items.

I tried to do a propfind with depth 2, but that somehow fails: server replied: Bad Request.

When he folder is expanded after pressing the arrow, and we find no children, the arrow should be removed. To do this, we have to emit a row/data changed signal and indicate that there are no children, which should make the arrow disappear.
